Starter Boil Duration
« on: May 01, 2013, 05:32:00 AM »
I used to always boil my starters for the perfunctory 10 minutes.  Lately, as I see the boil rolling, I'm taking it off after 5 minutes, mainly because I feel it's done and there is no reason to waste another  5 minutes on it. 

So, what's the issue I could be running in to?  I have not seen any issue with the starter itself.

The only reason I know for the boiling is sanitation.
If your starters are turning out fine and the beer you ferment with the yeast is turning out fine, then a 5 min boil is working for you.
I boil for 10 min just because I do and its only another 5 min.

This will likely ruffle some feathers but, for sanitation it is only necessary to bring it to a boil.

I agree with zimaclone, and would add anything over 145* will make it safe. So if you think about the amount of time it takes to get it from that to boiling and then back down below you should be good to go.

i think you do want to create some hot break with the wort - bringing it up to 145 won't do that I don't think.

I do 10 min cause that's what I've always done - no special reason other than it works.  YMMV.

I agree with that too.  I'm not an expert on extract or anything but I still would think you want a hot break, no?

LOL, I just clicked through.  I always did 10 mins too, but after hot break I'm like: "why am I standing here?"  If I make 30 starters a year and save 5 minutes on each, then I get 2.5 hours of my life back....

Why wait for the hot break if you're not going to separate the trub anyway?

Hmmm.  Good question.  I thought it made it more fermentable.

Well, 145F is pasteurization temp, but it must be held for 30 minutes to be effective at that low temp. And don't confuse pasteurization with sanitized. Pasteurization only kills most organisms, not all. That is why ultra-pasteurized milk can be stored longer than pasteurized milk. Higher temp = more dead organisms.
I would agree though that once it boils for a minute or two, you can take it off - even let it sit and cool slowly if you want. The wort is still hot with the burner off.  I do like to boil for a while so the steam will also sanitize my flask and foam stopper.

This is why I boil for ~5 minutes for my starters.  You could also sanitize them with starsan or something.

I bring to a boil in the flask and set the timer for 10 minutes while I do assorted other tasks then chill and pitch. Nearly Effortless. :)

Ron,

Agreed.  But I'm wondering if it needs to be 10 minutes or can you get 5 minutes closer to effortless?   :)
